Orifice meter

1. The principle of orifice meter - introduction

Orifice meter is the standard orifice differential pressure transmitter with multiple parameters of form a complete set of high contrast range pressure flow device, capable of measuring gas, steam, liquid and flow, widely used in petroleum, chemical industry, metallurgy, electricity, heating, water supply in areas such as process control and measurement. Throttling device, also known as differential pressure flowmeter, is composed of a test piece and the second device is widely used in gas. Steam and liquid flow measurement. It has a simple structure, convenient maintenance, stable performance.

2. The principle of orifice meter - classification

Orifice meter since application in industry, expanding the scope of its application, the original product specifications and standards to better adapt to the development of the rapidly changing industrial machinery, so the production of the orifice meter researchers according to the needs of various industries have developed two kinds of can adapt to the demand of orifice meter, mainly includes the orifice meter gauge integration and intelligent orifice meter two kinds. Integration of orifice meter is measured flow differential pressure generator, and intelligent orifice meter is integrating flow, temperature and pressure detection, the function is strong, compact structure, simple operation, easy to use.

3. The principle of orifice meter

Orifice flowmeter measurement flow is the principle of differential pressure generator, cooperate with all sorts of differential pressure gauge or differential pressure transmitter to measure all kinds of fluid flow in pipes, fluid filled with pipes, when they flow through the pipe of the throttle device, a beam to local contraction at the throttling of the throttle device, so that the flow velocity increases, the static pressure is low, so the throttling parts before and after the pressure drop is produced, the pressure difference, the greater the flow of medium flow, in the front and rear of the throttling parts the greater the pressure difference, so the orifice meter can be measured by the size of the pressure difference to measure fluid flow. This kind of measurement method based on the energy conservation law and the law of flow continuity as a benchmark.
